Patriot Camshaft

Introducing the Patriot Series DLC Coated Camshafts, the latest innovation from ATL Diesel’s premium Patriot product line. Built exclusively for heavy-duty Caterpillar and Cummins engines, these camshafts combine American engineering with Diamond-Like Carbon (DLC) surface technology to deliver unmatched durability, efficiency, and performance.

As the only company in the USA offering DLC coated camshafts for heavy-duty applications, ATL Diesel once again raises the bar with the Patriot Series — where cutting-edge technology meets Above the Line quality.

Key Benefits & Technical Advantages

• Patriot Tough Durability – DLC coating forms an ultra-hard surface layer that dramatically reduces wear, protecting lobes and journals from scuffing, pitting, and premature failure.

• Reduced Friction & Heat – DLC’s low-friction properties minimize drag, lower operating temperatures, and enhance lubrication efficiency.

• Extended Service Life – Outlasts conventional hardened camshafts, keeping trucks on the road longer and reducing downtime.

• Improved Fuel Economy – Less resistance equals more efficiency, translating into real savings at the pump.

• Maximum Power & Consistency – Ultra-smooth valve actuation improves airflow, horsepower, and torque — perfect for high-performance builds and tuned applications.

• Chemical & Corrosion Resistant – DLC shields against oil acids, fuel contaminants, and harsh duty cycles.

• Proven Patriot Performance – Engineered to excel in both fleet reliability and heavy-haul performance environments.
